struction hereinafter described and claimed, it The bearing supporting members 24 are each being understood that various changes in the mounted in an end frame between upper and 55 lower blocks Hand 26 respectively. The members 24 are arranged eccentric to the roller I4, as shown in Fig. 3, and each has one of the gear segments I6 secured thereto whereby it may be rotated between blocks 25 and 26, and due to its eccentric mounting raise and lower roller I4 relatively to table I5, to adjust the pressure thereof upon a matrix and a type plate disposed therebetween. The blocks 25 and 26 aremounted in the end frames I2 and I3 for vertical sliding movement and are constantly being urged upwardly by springs 27 provided to engage the lower block 26 and react against the adjacent part of the frames I2 or I3.

Between each of the upper blocks 25 and the adjacent part of the frames I2 or I3 is disposed a pressure responsive device, herein in the form of metal bellows or Sylphons 28, there being two of such devices used at each end of the roller I4, in this instance. The interiors of each of the bellows 28, at each end of the roller M, are connected by passageways 29 formed in a plate 3|. The plates 38 form the top .member of the bellows 28 and are in contact with the adjacent part of the frames I2 or l3. The bellows 28 are filled with a suitable liquid and, as well known, are compressible lengthwise whereby pressure will be applied to the liquid contained therein. By the above described arrangement of' parts pressure applied to the matrix between roller I 4 and table I5 will be transmitted to the liquid in the bellows 28 tending to compress the same.

A tube 32 is in connection with the passageway 29 provided in the plate 3i disposed in the frame I3, and a tube 33 is in connection with the passageway 29 in the plate 3i disposed in the frame I2. The tubes 32 and 33 are directed into a gauge casing 4I wherein they are in connection with the fixed end of Bourdon tubes 42 and 43 respectively.

The gauge casing 4i may be disposed in any convenient position on the machine and is herein shown secured to the frame l2 by means of a bracket 44. A suitable end cover ring 45, holding a glass cover 46, is provided for the gauge casing 4i, and through which a dial 4'?! and a pointer 48 are visible. The pointer 48 is connected to the end of a shaft 49, which in .turn, is connected to the free end of the Bourdon tube 42 by a lever 5| and a link em. Herein the shaft 49 is rotatably supported within a hollow shaft 52, on one end of'which the dial 4'! is secured. The shaft 52 is connected to the free end of the Bourdon tube 43 by a lever 53 and a link 53a'and is rotatably supported in a bearing member-54 formed as part of a gauge frame 55. Arrangements are such that, when movement of the Bourdon tubes takes place. due to pressure of the liquid in the system, or the release of such pressure, the pointer 48 will be rotated in one direction and the dial 4'! in the other, whereby the total pressure being applied by roller 94 maybe ascertained icy readings from the zero on the dial to the position of the pointer. The reading so obtained constitutes the sum of the pressure at each bearing of the roller I4 and is particularly accurate.

Arrangement may be made to indicate the amount of pressure at each bearing by providing a zero mark on the cover ring 45 as at 56. By providing indicia in both directions from this point comparisons of the pressure on either hearing may be ascertained by the deflection of either the dial Or the pointer 48 from the point 66.

The above described mechanism, in combination with the associated operable parts of a matrix rolling machine, is particularly useful in connecshaft bearing and who tion with the operation of such a machine to directly and visually indicate the pressure being applied by the roller substantially accurately, and by comparison to indicate the proportion of such pressure at each bearing. By proper adjustment of the bearings when the machine is being assembled equal pressure on each may be obtained whereby uniform pressure will be applied throughout the length of the roller i4 upon the matrix GI being pressed, and uniformly sharply defined impressions will be made therein over its entire area by the type form 82. The pads or blankets 63 are used to insure the flow of matrix material into the impressions on the type form 62 and as a cushioning means between the roller I4 and the matrix 6i.

It will be understood that the invention may be embodied in other specific forms without departing from the-spirit or essential attributes thereof, and it is therefore desired that the present embodiment be considered in all respects as illustrative and not restrictive, reference being had to the claims rather than to the foregoing description to indicate the scope of the invention.
